Discussion
Today-tonight... Ridge axis shifts south of the area, as frontal
boundary moves into the southeast united states today. A deep W sw
flow will exist across the region, and while overall pw values
remain around 1.8-2.0 inches, model guidance shows much drier air
moving in from the west between 700-500mb. This mid level dry air
and slight warming of temps aloft has lead to lower MOS pops across
the region this afternoon, especially across northern portions of
east central florida. Greatest chance for showers and storms is
forecast toward the treasure coast (around 40 percent) where
greatest moisture resides and lake sea breeze boundary collisions
are favored. Farther north and inland rain chances will be below
normal, generally ranging from 20-30 percent. Isolated stronger
storms will be possible, especially with any boundary interactions
near the east coast. Main threats will be frequent lightning
strikes, strong downburst winds and locally heavy rainfall.

Limited convection and offshore flow will contribute to high
temperatures in the mid 90s over much of the region, even along the
coast where east coast sea breeze is delayed into mid late
afternoon. Heat index values will continue to range from 100-105
most areas.

Saturday... Mid-upper trough (rather strong for late july) will dig
over the eastern CONUS and drive a frontal boundary into the
southeast states. This will cause the axis of the atlantic surface
ridge to be suppressed south of the state. Southwest winds will
increase and prevent the east coast sea breeze. This will allow max
temps to reach the mid 90s over most of the area. When combined with
surface dew points in the mid 70s, heat indices will continue in
the 100-105 range.

The GFS continues to have an uneven moisture distribution. The
model shows precipitable water starting off below normal, 1.6 to 1.7
inches, then shows a modest increase across the north in the
afternoon. Yesterday it indicated higher moisture in the south.

Rather warm mid level temps and the lack of an east coast sea
breeze suggest a low pop day. MOS values are below 20%, so will
just go with an areawide slight chance for afternoon showers storms.

Sunday-Friday... The trough aloft along the eastern seaboard is still
shown digging far enough south to shove a frontal boundary to near
the florida georgia border on Sunday. The 00z GFS even showed a weak
wind shift reaching our far northern sections late Sun and into mon.

Pre-frontal moisture band will start to affect the area on Sunday
and raise pops sharply after several days with below normal storm
coverage. The models show that even after the main trough lifts out
early next week, a piece of it will persist over the southeast
states and keep a deep moist southwest flow over the area through at
least mid week.

The increased rain chances and cloudiness will take a bite out of
the sizable MAX temps of late, with MOS showing highs in the upper
80s to around 90 degrees by Mon and continuing through the rest of
the period. Weakening and retrograding of the trough aloft is
indicated late in the week, which should allow the atlantic ridge
to build back north with a decrease in deep moisture. Plan to
keep rain chances around 60% through mid week then taper back to
40-50% after that.

Aviation Drier mid level air forecast to move into the region
should keep shower storm coverage more isolated over northern
portions of east central florida into this afternoon. Greater rain
chances will exist toward brevard county and the treasure coast with
boundary interactions that occur with the stalled east coast sea
breeze. Tempo ifr MVFR conditions will occur with any showers and
storms that develop, but due to lower convective coverage for much
of the area will only mention vcts in the tafs for now.

Marine
Today-tonight... High pressure ridge axis shifts south of the waters.

W SW winds up to 10-15 knots will become more southerly into the
afternoon and early evening due to sea breeze development. Seas will
generally range from 1-3 feet. A few stronger offshore moving storms
will be possible today, mainly mid to late afternoon from the cape
southward.

Weekend... Axis of atlantic surface high pressure ridge will get
suppressed south of the state. This will produce an increased
southwest wind flow. Speeds look to mainly be 10-15 knots, but
could be 15-20 knots well offshore. Seas will still only
marginally increase to 2 feet along the coast and up to 4 feet
well offshore.

Coverage of afternoon storms moving offshore on Sat will be low, but
then a pronounced increase is indicated on Sunday.

Mon-tue... The GFS shows a weak frontal trough sagging into our
northern waters. This should keep the pressure gradient light
there while southwest winds around 10 knots hold on in the south.

Seas 2 feet at the coast and up to 3-4 feet well offshore. High
moisture over the area will continue to fuel scattered-numerous
showers and storms (during both the day and night).
